    Developments in THz Polaritonics: Towards Integrated Nonlinear THz Spectroscopy by Sung, Eric Rueyhao

    Published 2024
    “…The optical pump light is focused onto the bevel, after which it refracts and becomes confined within the waveguide by total internal reflection. This allows the pump beam to repeatedly drive the generated THz field during its multiple back-and-forth traversals within the LN slab. …”

    Fabrication and characterization of graphene and carbon nanotube reinforced bioceramic nanocomposites by Hu, Huanlong

    Published 2020
    “…Bioceramics play an important role in the replacement and regeneration of human tissues, but their intrinsic brittleness and low wear resistance make the monolithic bioceramics still problematic for load-bearing applications. The two dimensional (2D) graphene and one dimensional (1D) carbon nanotube (CNT), as the secondary strong and tough biocompatible nanofillers, are popular nanocarbons to reinforce bioceramics. …”

    Compositionally graded alloys fabricated using the laser powder bed fusion technique by Wei, Siyuan

    Published 2023
    “…In this study, among the several available AM processes, the LPBF technique is selected to fabricate compositionally graded alloys, as it has higher spatial resolution and lower cost, compared to directed energy deposition (DED) and electron beam powder bed fusion (EBPBF). With three different LPBF setups and four alloy systems examined in this study, the following objectives are achieved: (i) screening out, from a large range of compositions, the alloys that are amenable to LPBF, (ii) examining the effects of the LPBF characteristics, e.g., rapid cooling rate, on the micro-/meso-structure and properties of the fabricated parts with varying chemical compositions, and (iii) evaluating the fabrication methods in terms of types of achieved gradation (stepwise or smooth), efficiency, and level of chemical segregation. …”

    Synthesis and characterization of Cu-Chalcogenide nanocrystals for potential applications in low-cost solar cells by Ahmadi, Mahshid

    Published 2013
    “…Since the opto-electrical properties of the NCs are highly dependent on the composition and crystal structure, X-ray diffraction, selected area electron diffraction, convergent beam electron diffraction and Raman spectroscopy were used to determine their crystal structure. …”
